Ahead of Health and Human Services Secretary Kathleen Sebelius’s appearance on the Hill, Sen. Pat Toomey on Wednesday stepped up his attacks on President Barack Obama and the administration on health care, charging they misled Americans on whether they can keep their existing coverage.

“How many times did the president promise people that if you like the coverage you have, you’ll get to keep it? We always knew that was untrue. Now, of course, it’s coming home,” Toomey (R-Pa.) said on Fox News’s “Fox & Friends.”

Toomey claimed the White House “knew all along” that some people would lose coverage.

“Now it turns out that this entire administration obviously knew all along that millions of Americans would not be able to keep their insurance even if they liked it,” Toomey said.

Toomey, who slammed the launch of Obamacare as an “incompetent rollout” and “disaster,” sits on the Senate Finance Committee that will question Sebelius on Wednesday.

“This is just a complete debacle. It’s hard to know even where to begin with Secretary Sebelius,” Toomey said, adding that she “needs to come up with some answers.”
